--- name: "kmos_std_star" section: "7" platform: "linux" package: "cpl-plugin-kmos-doc" version: "2.1.0+dfsg-1" release: "Debian 10 (Buster)" platforms: ["linux"] url: "https://new.carta.tech/kmos_std_star" --- # kmos\_std\_star(7) Create the telluric correction frame. ## NAME kmos\_std\_star - Create the telluric correction frame. ## SYNOPSIS esorex **kmos\_std\_star** \[OPTIONS\] FILE.sof ## DESCRIPTION This recipe creates a telluric frame and a PSF frames. Since there cannot be 1 std star per IFU in one exposure, we use several exposures in order to have at least one standard star and one sky in each IFU. The frames are organised following this logic: 1. For each IFU the first standard star in the list of frames is\ taken. All subsequent standard star exposures for this IFU are ignored 2. A closest in time sky exposure is uѕed 3. IFUs not containing a standard star and a sky will be empty in the result NOISE\_SPEC contains the shot noise \[sqrt(counts\*gain)/gain\] If the exposures have been taken with KMOS\_spec\_cal\_stdstarscipatt, an additional noise component is added: All existing sky exposures for an IFU are subtracted pairwise, spectra are extracted and the std deviation is computed Input files: DO KMOS \ category Type Explanation Required #Frames\ \-------- ----- ----------- -------- -------\ STD RAW Std. star & sky exposures Y \>=1 \ XCAL F2D x calibration frame Y 1 \ YCAL F2D y calibration frame Y 1 \ LCAL F2D Wavelength calib. frame Y 1 \ MASTER\_FLAT F2D Master flat frame Y 1 \ WAVE\_BAND F2L Table with start-/end-wl Y 1 \ ILLUM\_CORR F2I Illumination correction N 0,1 \ SOLAR\_SPEC F1S Solar spectrum N 0,1 \ (only for G stars) \ ATMOS\_MODEL F1S Model atmospheric transmisson N 0,1 \ (only for OBAF stars in K band) \ SPEC\_TYPE\_LOOKUP F2L LUT eff. stellar temperature N 0,1 Output files: DO KMOS \ category Type Explanation \ \-------- ----- ----------- \ TELLURIC F1I The normalised telluric spectrum \ (including errors) \ STAR\_SPEC F1I The extracted star spectrum \ (including errors) \ STD\_IMAGE F2I The standard star PSF images \ STD\_MASK F2I The mask used to extract the star spec \ NOISE\_SPEC F1I The extracted noise spectrum ## OPTIONS - **--startype** *\* The spectral type of the star (O, B, A, F, G) e.g. G4V (str; default: ´´).
